特徴とするモータ制御回路。 A power supply circuit includes a motor and a power transistor whose collector is connected to one end of the motor.
In a device that controls the rotation of a motor by controlling the base voltage of this power transistor by a drive circuit that receives commands from a microcomputer,
The microcomputer sets a set voltage, outputs this set voltage to the drive circuit, and the drive circuit compares this set voltage with the feedback voltage from the collector of the power transistor and adjusts the voltage of the power transistor according to the difference. In addition to controlling the base voltage, the above microcomputer also
A motor control circuit that compares the set voltage with the feedback voltage from the collector of the power transistor, and outputs a signal to stop power supply to the motor and the power transistor when the difference exceeds a predetermined value.
